South Central ND (06/07/18)

Information from the South Central region of North Dakota.

The region’s NDAWN station data indicate rain during the past week (May 30-June 5) ranged from 0.3 inch (Brampton and Oakes) to 2.7 inches (Streeter), with the Carrington REC receiving 1.6 inches. The combination of adequate topsoil moisture and warm soil temperatures is providing an excellent environment for crop establishment and accelerated growth of early planted crops.

Alfalfa is in the early bloom stage and first cutting has begun. Winter wheat is beginning to head and winter rye is flowering. Early seeded (late April) barley and spring wheat are jointing (5- to 6-leaf stages). Corn planted during the first week of May has 4-5 leaves. Soybean planting is essentially complete and dry bean planting should nearly be complete by the end of this week. Mid-May planted soybean is in the first trifoliate stage (V1) and dry bean is also in the first trifoliate stage (V1)

Application of POST herbicides for small grain and corn is in progress – weeds are doing as well as the crops! Currently a low incidence of tan spot is showing in small grain. Corn currently may be showing colors besides green (see picture). Reasons for corn leaf discoloration include wet soils, compacted soils, ‘fallow syndrome’ (see article on page 12), or low soil nutrient levels.
